LINER AND CAN CONSTRUCTION.

Application filed August 2, 1926. Serial No. 128,486.

My invention relates to liners and can construction and is particularlyadapted to a certain construction of can whereln it is desired toprovide a liner of a rust proof material and which is supported by anouter shell adapted to provide the necessary rigidity and firmness tothe can in an economical manner.

A feature of the invention resides in providing an aluminum liner for acan having an integral construction to provide the sides and the bottomto the can and designed not to add weight to the can proper. Thisaluminum liner is adapted to provide the rust proof means for lining thecan so that ice cream and other similar ingredients may be packed in thecan without any danger of rust affecting the same. My invention relatesparticularly to such articles where the ice water is salted so as tokeep the ice cream cold within the can and this salt water is inclinedto rust the can very easily, especially after becoming usedand slightlyworn and owing to the severe use to which they are subjected.

My invention includes a rust proof l1ner which is adapted to besupported by the outer shell of a reinforced material having an upperribbed construction for the top and a lower depending flange to form afoot on the can, while a suitable plate member is projected into thelower flange portion to provide a bottom of reinforcing material toprotect the liner. In uslng the rustproof liner of aluminum, a rathersoft rust proof 'material, it is necessary that the same be reinforcedproperly to prevent bending and injury to the same so that the can Wlllkeep the proper shape inside and out.

These features together with other ob ects and details of my inventionwill be more fully and clearly set forth in the following specificationand claims.

In the drawings forming part of the specification Figure 1 is aperspective view of my can and the liner for the same.

Figure 2 is a cross section of my can showing a portion broken away.

In the drawings my can A is designedof a nature so as to provide theouter remforcing shell 10 which is made of heavy tm or galvanized metalso as to provlde an outer shell strong and durable and: constructed soas to be wear resisting. The shell 10 is preferably tubular and 18formed with an upper reinforcing head 11 having an annular constructionto provide areinforcement at the top of the can and also to provide ashoulder for the cover to hold the same, the cover not being illustratedin the drawings.

A feature of my invention is to provide a simple structure for an icecream can which is provided with a rust proof or non-corrosive lining 12made of aluminum or other suitable material having an integral nature,so that the side walls 13 of the same, are formed integrally with thebottom 14:. This liner 12 is-slid into the casing 10 and is adapted tobe beaded over at 15 around the upper edge of the can A to provide asmooth rust proof edge over the top of'the can. This is important in icecream cans as it is not desirable to have the rust come in contact inany place with the ice cream. i

The casing 10 is. formed with a foot portion 16 extending below thebottom 14 of the can A in a manner to form a support for the can and toraise the bottom 14 of the liner away from the bottom edge of the casing10. This permits the insertion of a disk or plate member 17 of strongmaterial similar to the construction of the casing 10 so as to form areinforcing bottom and a protecting disk for the bottom 14 of the can A.This bottom is forced into the casing shell 10 and is held by frictionin place against the bottom 14.

The structure of my can is very simple and it is designed to overcomethe necessity of using paper liners in ice cream cans and to permit theouter reinforcing shell of the can to be made of heavy iron which may betinned or otherwise coated so as to be rust resisting, yet not havingthe expensive construction of being made entirely of aluminum or otherrust proof material which ordinarily is of a softer nature and is notstifi' enough to stand the wear and tear to which ice cream cans aresubjected in ordinary use. I

The tubular shell 10 provides an inexpensive structure for the containerA when used with my aluminum liner, particularly for the. reason that noliquid tight joints are necessary in the casing 10 as the casing can bemade of a seamless tubular material or the seam may be riveted in adesirable manner. The reinforcing bottom 17 which is also made of heavywear resisting material, is merely forced into a position against thebottom 14 of the aluminum liner so that the s assembly and manufactureof my ice cream can is very simple and inexpensive. After the liner 12has been forced by friction into the casing 10 the reinforcing bottomdisk 17 is forced up against the bottom of the liner, providing the footor flange portion 16 for the casing and can A and forming a reinforcingmember across the bottom to prevent bending or denting of the can, therib 11 at the top reinforcing the upper end of the can to provide thenecessary rigidity. I When the liner 14 has become worn and it isdesirable to replace it, "this liner can be forced out at the bottom,forcing the reinforcing disk 17 out of the casing 10 and the liner 12removed 'so that a new liner can be placed'in the can.

I have found in practical use that my aluminum liner fdr an ice creamcan with a reinforced shell 10 is much to be preferred over the paperliners which are now used to prevent the rusting of the can affectingthe contents or the ice cream within the ice cream can. The simplicityof my invention adds to the merit, and the demand for the same evidencesthe practical nature of my invention. It is apparent that the liner maybe quite thin by reason of the reinforcin casing which protects thesame.

y can is also intended to be used as a container for milk, or otherdairy products that are better protected by the rust proof linerprovided for in my can. It is quite apparent that with dairy products acontainer of this kind is very desirable because the outer body portionor casing of the can can be made of strong material, while the innerliner can be made of aluminum or other soft non-rusting metal.

In accordance-with the patent statutes I have described the principlesof construction of my liner and cam-together with the best embodimentthereof illustrated in the accompanying drawings, and.- while a par--ticular formation is shown, I desire to haveit understood that it isonly suggestive of a means of carrying out my invention and that thesame may be carried out by other means and applied to other purposeswithin the scope of the following claims. a

-I claim:

. 1. A can including, an outer reinforcing casing having a tubularstraight wall construction, a liner formed of aluminum adapted to fitover the upper edge of the can, and a reinforcing bottom diskfrictionally supported spaced from the lower edge of the casing andadapted to protect the bottom of said liner.

2. A can including, a liner formed of aluminum, an outer reinforcingshell adapted to frictionally engage said liner in a manner to permitthe liner to be removed, and a bottom reinforcing disk adjacent theliner frictionally supported within said reinforcing casing to provide areinforcing bottom inset portion for said can.

3. A can including, an outer metallic reinforcing shell having a tubularnature, an inner metallic rustless liner and a reinforcing bottom diskfrictionally supported within said shell, said disk being removable topermit the liner to be forced out of said 1 shell so that the liner maybe replaced.

4. A can having a rust proof liner oomrising an outer tubular shell, anintegral iner having a bottom portion adapted to be frictionallysupported within said shell, an annular bead on saidlineradapted tocover the upper edge of said shell and to form-a shoulder for holdingsaid liner positioned in said shell, and a reinforcing and supportingdisk frictionally supported and spaced from the loweredge of said shelland adapted to bear against the bottom of said liner.

.5. A can including, an outer heavy metallic shell, an inner rust proofand non-corrosive lining havin an integral bottom formed therein, an aheavy reinforcing disk frictionally supported against said bottom ofsaid liner to protect the same.

6. An ice cream can including, a metallic rust proof her having acylindricalstraight wall construction, an integral bottom formed in saidliner to provide a seemless rustless lining member, and an outer casingadapted to protect said liner against wear including a disk like bottommember formed from a separate iece of material and adapted to befrictionally supported spaced from the bottom of said casing and bearingagainst the bottom of said liner.
